Validity of an updated nutrition literacy assessment instrument with the new nutrition facts panel.

This study aimed to determine reliability of the NLit subscale using two NFP versions. A 35-item survey was administered to 48 attendees with very low incomes. Surveys included previously validated NLit numeracy questions referencing the Current NFP (C-NFP), demographic and financial literacy questions, and the same NLit numeracy questions referencing the New NFP (N-NFP). NLit numeracy between the C-NFP and N-NFP were related (r = 0.842, p < .001), and N-NFP showed excellent reliability (Cronbach-α = 0.815). Mean NLit numeracy scores for the C-NFP and N-NFP were 53.5% and 55.5%, respectively (p = .437). Exchanging the N-NFP for the C-NFP in the NLit maintains strong reliability. Similar numeracy scores between C-NFP and N-NFP suggest the redesign may not be easier to read.
